FLOOD-GATE.

SPECIFICATION forming part of Letters I atent No. 461,114, dated October13, 1891.

Application filed May 13, 1891- Serial No. 392,595. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH Hmson, a citizen of the United States,residing at Centre, in the county of Mercer and State of Ohio, haveinvented a new and useful Flood-Gate, of which the following is aspecification.

My invention relates to an improvement in flood-gates; and it has forits object to provide a simply constructed and operating gate that willreadily open with the rise of water and close with the fall of the same;and it consists of a specially-constructed gate-operating devicehereinafter more fully explained, illustrated in the accompanyingdrawings, and specifically pointed out in the appended claims.

In the accompanyingdrawings, Figure 1 is an innerperspective ofaflood-gate constructed in accordance with myinvention, thegates beingin their normal position. Fig. 2 is a front elevation of my improvedflood-gate, the gates being open.

Referring to the accompanying drawings by'letter, A A designate the sideposts, )rovided with the usual extended portions to a, that are adaptedto be driven in the ground to hold the frame-Work securely anchoredthereon. The said side posts are connected together by the upper andlowerbraces B and B, respectively, against which the gates C, hinged tothe side posts by the ordinary hinges c, are designed to rest in theirclosed position. The gatesO are constructed of the ordinary material andin the ordinary manner and are designed to be swung open and closed,according to the rise and fall of the water. On the side of the posts AA opposite the sides on which the gates are hinged and at their lowerextremities at the bottom of the gates are hinged the converging arms DD, that meet in a point and are suitably braced together by theconnecting brace and weight (1, forming a triangular frame, the samebeing designed to act as a weight for holding the gates in their closedposition.

Chains or ropes E connect said triangular gate-operatin g weight withthe gates by means of eyebolts or staples c, secured in the free ends ofboth of the gates and in the diverging arms of the triangular frame neartheir meeting points.

It is thought that the operation of this gate will be apparent from theforegoing description. As the water from the flood or enlarged streamstrikes the said triangular frame the same rises up and assumes avertical posit-ion, bearing against the cross-braces connecting the sideposts, and permits the gates to be thrown open by the water and allowthe same a free and unobstructed passage-way.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a tloodgate, the combination, with the swinging gates, of an opentriangular frame hinged to the gate-posts at their lower extremities,and chains or ropes connecting said gates and said triangularframe,substantially as set forth.

2. In a floodgate, the combination, with the gate-posts andcross-braces, of the outwardlyswinging gates hinged to said posts,converging arms hinged to the posts at their lower extremities, the samemeeting in a point and held together by a cross-brace, and chains orropes connected to the upper edges of each gate and the extremities ofsaid converging arms, substantially as set forth.

'lhe combinatiomwith the swinginggates, of converging wooden beamshinged to the gate-posts, and ropes or chains connecting said beams tothe gates, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JOSEPH HIRSCH.
